Preheat the oven to 425°F.
Rinse and pat dry the salmon fillet. Season lightly with salt and pepper.
Peel the sweet potato and cut it into 1/2-inch cubes.
Trim the asparagus, removing the tough ends.
In a bowl, toss the sweet potato cubes with salt, pepper, and a small drizzle of olive oil.
Spread the sweet potatoes on a baking sheet and roast in the oven for 20 minutes, stirring halfway through.
While the sweet potatoes are roasting, heat a non-stick skillet over medium-high heat. Sear the salmon, skin-side down if applicable, for about 3-4 minutes per side, until just cooked through.
In the last 10 minutes of sweet potato roasting, add the asparagus tossed with 1 tsp olive oil, salt, and pepper to the baking sheet.
Once all components are cooked, plate the seared salmon alongside the roasted sweet potatoes and asparagus.
Serve immediately and enjoy your balanced dinner.
